Set up diagnostic logs via the Azure Monitor REST API

  • आलेख

This article describes how to set up diagnostic logs for Azure Data Factory by using the Azure Monitor REST API.

Diagnostic settings

Use diagnostic settings to configure diagnostic logs for noncompute resources. The settings for a resource control have the following features:

  • They specify where diagnostic logs are sent. Examples include an Azure storage account, an Azure event hub, or Monitor logs.
  • They specify which log categories are sent.
  • They specify how long each log category should be kept in a storage account.
  • A retention of zero days means logs are kept forever. Otherwise, the value can be any number of days from 1 through 2,147,483,647.
  • If retention policies are set but storing logs in a storage account is disabled, the retention policies have no effect. For example, this condition can happen when only event hubs or Monitor logs options are selected.
  • Retention policies are applied per day. The boundary between days occurs at midnight Coordinated Universal Time (UTC). At the end of a day, logs from days that are beyond the retention policy are deleted. For example, if you have a retention policy of one day, at the beginning of today the logs from before yesterday are deleted.

Enable diagnostic logs via the Monitor REST API

Property Type Description
storageAccountId String The resource ID of the storage account to which you want to send diagnostic logs.
serviceBusRuleId String The service-bus rule ID of the service-bus namespace in which you want to have event hubs created for streaming diagnostic logs. The rule ID has the format {service bus resource ID}/authorizationrules/{key name}.
workspaceId String The workspace ID of the workspace where the logs will be saved.
metrics Parameter values of the pipeline run to be passed to the invoked pipeline A JSON object that maps parameter names to argument values.
logs Complex Type The name of a diagnostic log category for a resource type. To get the list of diagnostic log categories for a resource, perform a GET diagnostic settings operation.
category String An array of log categories and their retention policies.
timeGrain String The granularity of metrics, which are captured in ISO 8601 duration format. The property value must be PT1M, which specifies one minute.
enabled Boolean Specifies whether collection of the metric or log category is enabled for this resource.
retentionPolicy Complex Type Describes the retention policy for a metric or log category. This property is used for storage accounts only.
days Int The number of days to keep the metrics or logs. If the property value is 0, the logs are kept forever. This property is used for storage accounts only.
